A) \[Q\,\not\subset P\]
B) \[P\,\not\subset Q\]
C) \[P\subset Q\,\]and \[Q-P\ne \phi \]
D) P = Q
Correct Answer: D
Solution :
For Let P \[\sin \theta =\cos \theta (\sqrt{2}+1)\] \[(\sqrt{2}-1)\,\sin \theta =\cos \theta \] ....... (i) For Let Q \[\cos \theta =(\sqrt{2}-1)\,\sin \theta \] ?.... (ii) (i) & (ii) are same P = QYou need to login to perform this action.
